How to add View-port colour and View-port specular to object in cycle render.?
what you have is this:



what you want is something like this:



what you miss is two things:

There is no light source in the scene. You can have lamps like in the following screenshot, ore use an image in the world background (yours is monochrome), or combine both.



the material setup only has a diffuse shader to it. This shader will only return diffuse color information, so specular lights won't show up anyways, no matter what you try. Mix the shader with for example a Glossy shader, which catches some reflection:



from here you can take it to however sophisticated you want. Add fresnel, maps, vertex colors, whatnot, but without proper material setup and proper lighting, no scene can look cool  :)
